Some janitor at my school had an '88 LX Notchback with a full MAC Exhaust that sounded pretty good. One of my friends has a '96 GT 5spd, with a UPR Off-Road X-pipe with BBK long-tube headers and a Flowmaster American Thunder cat-back system which sounds loud and good. I have a Mac Off-Road H-Pipe, MAC 1 5/8 Equal Length Headers, MAC Tailpipes and Flowmaster 10 series Delta Force (1 Chambered) race mufflers which are extremely loud. My cousin UnderPressureGT has DynoMax Race Bullets which are very loud also. There are a lot out there, even Spintech Pro Streets have a good sound. If you get an X-Pipe it will sound raspy, but nice, and if you get a H-Pipe it will sound deeper and louder than the X-Pipe. Hope you pick a good one.
